Title: Circular ultrasonic vibration element
Inventor: OOYA KANJI
IPC: B08B3/12
Filed: 1979-03-09
Abstract: PURPOSE:To radiate an even ultrasonic wave from the broad irradiation surface of a diaphragm by concentrically connecting many piezoelectric transformers to the circumference of one piezoelectric transformer, coupled with the center part of the surface of a diaphragm piece, at intervals of one-fourth wave-length of transverse vibration. CONSTITUTION:When piezoelectric converters 12a-12c coupled with circular disphragm 11 in a fixed pattern are drived in phase at a time at the same frequency, parts 11a, 11b and 11c of the diaphragm coupling center, intermediate and external piezoelectric converter groups 12a, 12b and 12c are amplitude-displaced as shown by small curves (b), (c) and (d) and longitudinal vibration of amplitude displacement like curve (e) on the whole can be obtained. Then, the impedance of external circumference piezoelectric converter group 12c is minimized and that of center piezoelectric converter 12a is maximized or center piezoelectric converter 12a is connected out of phase, so that the diaphragm can longitudinally be vibrated with a uniform amplitude value over its entire surface.

Filed: 1982-02-24
Abstract: PURPOSE:To presume easily and surely inner temperatures of a blast furnace or cracks  and its generation time of a refractory material, by measuring the alteration of stress  of an iron shall by a strain gauge stuck to the outer surface of the iron shell of the  blast furnace. CONSTITUTION:A fire brick is constructed on an iron shell 1 taken out a part of the outer wall part of a blast furnace through a stamping material 2 and a test machine restricting transformation in the circumference direction of a refractory material  3 by the shell 1, a side plate 4 and a tension bar 5, is prepared. Further, the inner surface of the refractory material is heated by a heater 6 and the strain of the iron  shell is measured and then, the temperatures or cracks of the refractory are observed.  By this observation result, as the inner surface temperature of the refractory material  is raised, the stress of the iron shell is increased and then, it is saturated at some  point. The stress is lowered suddenly and cracks are generated in the refractory material at the same time by continuing heating moreover and then, projection to the  heating side is observed. Also, an echo of acoustic emission is detected. Accordingly,  sudden reduction of the stress of the iron shell shows the generation of the cracks in  the refractory material. Hereby, the inner temperatures of the blast furnace or the  cracks and its generation time are presumed.

Inventor: KAWASAKI TOSHIHISA
IPC: H05B7/10
Filed: 1990-02-08
Abstract: PURPOSE:To restore with ease melting losses of an electrode by providing a gripping clamp for a bottom electrode of a furnace and a holder for releasing the clamping, and a jack for lifting the electrode a predetermined amount. CONSTITUTION:A holder 7 consists of a holding cylinder 7b in slidable engagement with a bottom electrode 6 of a furnace and an annular water jacket 8, whereby by the mutual wedge action between the outer tapered surface 7c of the cylinder 7b and the inner tapered surface 8a of the jacket 8, a gripping clamp or the electrode 6 is locked or released. And a jacking device 22, when necessary, releases the clamping of the holder 7 to jack up the electrode 6 a required amount. As a result, during the repair, the electrode 6 is lifted by an amount of melting losses so that thereafter the stump of refractory material can be repaired by an amount corresponding to the melting losses. Further, on account of the mutual wedge action of tapered surfaces, the holder functions surely in a simple manner, so that safety work can be performed.

Title: Image forming device
Inventor: TAKAHASHI KOICHI
IPC: G03G15/01
Filed: 1995-02-17
Abstract: PURPOSE: To obtain performance equal to that in the case of non-contacting condition even in a condition that a photoreceptor is brought into contact with developer by changing the value of a developing bias used in each image forming device to a value closer to that of an intermediate potential side than a normal value. CONSTITUTION: Developing is prevented by stopping the developing rolls 14 and 18 of a first and a second developing devices 7 and 8 in the time of starting-up and termination of electrification. Since the developer 16 and the developer 20 are easily brought into contact with the photoreceptor 1 at this time, the value of the developing roll bias is made close in a specified value direction so as not to exceed the specified value in the range of 100 to 300V not at the normal set value but at the absolute value. Thus, carrier is prevented from adhering to the photoreceptor 1 from the developer 16 and the developer 20 on the rolls 14 and 18 while the developer is brought into contact with the photoreceptor 1.  In the case of the starting-up of electrification, the rolls 14 and 18 are operated after a surface potential sensor 5 stabilizes the value of the intermediate potential part to be a value within ± fifty to sixty V centering the specified value, and the developing roll bias is returned, and in the case of the fall of the electrification, the bias is operated to be disconnected as the photoreceptor 1 is stopped rotating.

Abstract: PURPOSE:To prevent the break of a machining tool in the rushing stage thereof without any increase in man-hour for preparing machining data by adding a preliminary bore machining data generation part and controlling a contour processing machine on the basis of the machining data and a rush point preliminary bore machining data. CONSTITUTION:Upon the start of a contour machining, the CPU 31 of a preliminary bore machining data generation part 3 receives machining data from a data input part 1, reads the data and causes RAM 33 to store the data of a machining tool diameter. Then, upon reading machining start point data about a machining shape from the input part 1, the CPU 31 generates rush point preliminary bore machining data having the same diameter value as the machining tool and delivers this data to a contour machining control part 2, using the same coordinate value as a machining start point position, when the machining tool diameter stored in RAM 33 is smaller than a boundary reference value saved in ROM 32. Subsequent thereto, the machining start point data as machining data is delivered to the contour machining control part 2 without any modification.

If plating is applied on said surfaces by using an anode plate 16 in this state, the metallized surfaces 2 glide laterally and slide little by little by maintaining contact with the surface of the mesh 31, thereby receiving the plating uniformly.

Title: Diaphragm pump
Inventor: KARIYA TOKUJI
IPC: F04B43/02
Filed: 1982-02-25
Abstract: PURPOSE:To hinder drop of the volume efficiency and discharge amount by making the diaphragm in a construction with increased mold strength on the compression side, minimizing the compression space in order for the top part not to touch at the amplitude of electromagnetic vibration, and thereby suppressing re-expansion as much as possible. CONSTITUTION:Diaphragms 14, 14' are so formed as an upper fulcrum for compression in natural state and equipped with a projection 14a. If the strength of the diaphragms 14, 14' is set so as to be the sum of discharge pressure applied to diaphragms subtracted by the electromagnetic attractive force, with the above-mentioned state held, by means of the overall molding with the projection 14a in its center, no rightwise negative force owing to the discharge pressure will be in action in the compressive position, and therefore drop of discharge amount can be hindered without causing decrease of vibrative stroke. Then under compression stroke, suction and discharge valves 15, 15' and 16, 16' are set so that the compression spaces 19, 19' become the minimum volume. Thus drop of the volume efficiency can be prevented.
